At first this puzzle looks like a Square-1 which the middle layer was removed or hidden. Contrary to this first look the puzzle has a completely new mechanism designed from scratch. This new mechanism allows for a strange unporecedented behaviour.The angles of the pieces are new too. The pieces of Square-1 have angles of 30° and 60°. The pieces of this puzzle have 36° and 54°.Edge length: 50 mm
